Abstract
A method for producing a fiber reinforced plastic can suppress with which wrinkling or bridging in a convex surface or a concave surface having a large curvature at the same time even if the fiber reinforced plastic has a complicated three-dimensional shape. Such methods for producing a fiber reinforced plastic may involve shaping a prepreg sheet in which continuous fibers are impregnated with a resin material into a three-dimensional shape to produce a fiber reinforced plastic (a); wherein at least a portion of the continuous fibers in an area (X) of the prepreg sheet corresponding to an area (X') in which the fiber reinforced plastic (a) is shear-deformed is bent in an in-plane direction in advance.
